MATERIAL FOR TREATING COPPER.

No Drawing.

To all whom it may concern:

Be it known that I, JULIAN KIoH, residmg at Lyndora, in the county of Butler and State of Pennsylvania, a subject of the Emperor of Austria-Hungary, have invented or discovered certain new and useful Improvements in Material for Treating Copper, of which improvements the following is a specification.

The invention described herein relates to certain improvements in the treatment of cop er whereby it is increased in hardness an in other respects.

In the practice of my invention, I employ several compounds which are formed as follows: 1

No. 1 consists of the following ingredients in approximately the proportions stated 2% oz. welding compound, goz. copperas or ferrous sulfate, oz powdered bones, e oz. ferro-silicon, T} oz. potash, 3; oz. limestone. The principal ingredients of this welding compound are: boric anhydrid, iron oxid 15%, soda 15%, and potash in 20 Z; in about the proportions stated. The ingredients of this compound are finely powdered and thoroughly mixed together. and about 183% of this mixture is added to about 81.4% copper, when the latter has been sufiiciently melted to permit of the stirring in of the compound. This mixture added to the copper renders the same very hard and dense.

A somewhat softer material may be produced by adding to 87%% of copper 12=1-% of a'mixture consisting of oz. limestone, oz. potash, 1 oz. ferrosilicon.

Specification of Letters fatent.

npplication filed March 21, 1912. Serial No. 685,388.

A third mixture which will produce good results, if added in the proportion of 25% peras or ferrous sulfate, oz. sulfate of copper, oz. ferro-silicon, oz. potash, oz. limestone, oz. manganese, oz. phosphorus.

A fourth mixture, added in about the proportion of 15?;% to 84-1 copper, while not producing as hard and dense a material as the mixture heretofore stated, will produce one useful for many purposes. This; mirture' consists of ferrosilicon, potash, phos phorus, welding compound, limestone, of each of the above materials.

It will be observed that each of the fore going mentioned mixtures contains as a base, or common ingredients, potash, ferrosilicon, and limestone, and that the effects produced by the mixture of these three ingredients is modifiedyi 6., increased or di minished by the addition of the other elements stated.

I claim herein as my invention:

1. A material for treating copper consist:- ing of, potash, ferro-silicon, and limestone.

2. A material for treating copper consisting of potash, ferro-silicon, limestone, and a welding compound.

In testimony whereof, I have hereunto set T my hand.
